Improvement in machines for shelling pease



UNITED STATES ATENT Bric IMPROVEMENT IN MACHINES FOR SHELLING PEASE.

Specification forming part of Letters Patent No. 56,370, dated July 17, 1866.

To ZZ whom 'it may concern:

Be it known that I, GEORGE CLARK, Jr., of

-I Boston, Suffolk county, State of Massachusetts,

have invented a new and Improved Machine for Shelling Pease and other Seeds from their Oontainin g Pods 5 and I do hereby declare that the following is a full and exact description ot' the same, reference being had to the accompanying drawings, with letters of reference marked thereon, all ot which, taken together, form my specification.

In the drawings annexed, Figure l is a front view of my machine. Fig. 2 is a view from "the back and Fig. 3 is a vertical section through the center. y

In the drawings, A B B, Fig. 2, show a metallic frame consisting of a horizontal bar, A, with a strengthening-rib, A", beneath, supporting two upright bars, B B, Fig. 2, which ris'e perpendicularly parallel to each other. To one of these upright bars or standards are attached two projections, O O, Figs. l and 2,

4 vprojecting horizontally and placed about one and one-fourth inch apart. Through the un- -VVVder one of these projections passes perpendicularly a thumb-screw, D", Figs. l and 2, the two projections and the screw forming thus a screw-clamp. The use of the screw-clamp is to fasten the machine to the edge oi' a table or shelf. I

Supported by the uprigh ts B B are two horizontal. rollers, D D, Figsf2 and 3, running parallel to each other. The shafts or pivots Dx D", Fig. 3, run through the center of them and work in circular bearings in the uprights B B. These rollers run within about one-six- ".teenth of au inch of each other.

To the shaft of each roller is attached a cogwheel, E E, Figs. l. and 2, and to the shaft of the lower roller is attached a crank, F, and handle G, Figs. 1 and 2. By the turning ot' this crank both rollers are made to rotate.

To the front of the frame (see Fig. 1) is attached what I call a face-plate, being a metallic plate, I, Fig. 1, and I I, Fig. 3, fastened to the frame by means of the ears H H, Figs. l and 2, and H, Fig. 3. This plate runs perpendicularly in front of the rollers, at about 'the distance ot' three-fourths of' an inch from them, (see Fig. 3,) and has inl its center an oval aperture, (seen in Figs. 1 and 3,) and attached to its lower end a spout, J, Figs. 1, 2, and 3. Y

K, Figs. 2 and 3, is a plate, called the scraper, fastened to the rear side ol the trame on the bar A, its upper edge comin close tov the lower rolls, as seen in Fig. 3.

The operation ol the machine is this: The

`machine being screwed to the edge o1" a table by means of the screw-clamp, the rollers are made to rotate by means ot' the crank. The pea-pods meanwhile are led with the other hand through the aperture ol the face-plate. (Seen in Fig. l.) The rotating .rollers seize the end ot' the pod and, drawing the same bctweeu them, force the peas from their attachment to the pod, and as the peas, owing to their size, cannot pass between the rollers, they are foreedbutot' the split pod, and being prevented from flying away and scatterin by the face-plate, they fall downward and are guir'led. by the spout beneath into some convenient rcceptacle placed beneath i'or that purpose. As the pods are somewhat crushed by the acti on ot' the rollers, they would be liable lio adhere in portions to some extent on the rollers, more particularly the under one; but the scraper scrapes these portions oli' and prevents the clogging et' the rollers. l

I make my rollers either otl wood., otl metal, or of other substance, and I sometimes have them tluted and sometimes plain; and Imake my frame and face-plate of either metal or wood, and l sometimes place them vertically or diagonally; and I sometimes combine seyeral pairs oi" rollers in one machine 5 and. I sometimesattach another spout to the rear side ol" the machine to convey away the pods; and l sometimes use the machine'for shelling beans or other pod-contained seedsl as well as peas.

. What I claim herein as of my own invention, and desire to secure by Letters Patent, is-

. The combination ot' rotating rollers, faceplate, and screw-clamp, whether with or without the scraper, for the purpose of expressin peas and other seeds from their containing- Vessels, when the same are constrnclxnl and used substantially as described.
